FULL-STROKE MECHANISM.

To all whom it may concern:

Be it known that I, HENRY KtiN'rzLnR, a citizen of the United States, residing at Kingston, Luzerne county, Pennsylvania, have invented a new and useful Improvement in Full-Stroke Mechanism, of which the following is a specification.

This invention relates to full-stroke mechanism for registering machines and is adapted in particular for such of these machines as are operated either manually or by power. Its principal object is to maintain the full-stroke mechanism in operative condition when the machine is manually operated and automatically to disconnect it when the machine is to be power driven. In the latter instance the full-stroke mechanism is not only needless, but it is also a hindrance to high operative speeds otherwise attainable by a power drive; as the usual spring-actuated locking dog coacting with the notched sector cannot change its position quickly enough at the end of the working stroke to function properly.

The invention consists in certain novel features of construction and combinations of parts the essential elements of which are set forth in the appended claims and in the preferred form of embodiment disclosed in the accompanying drawings and description. The embodiment is shown in connection with a calculating machine, the latter being a typical example of a registering machine to which the improvement may be applied.

The particular machine selected to illustrate the operation of the invent-ion is the Wales adding machine as shown and de scribed in Letters Patent Nos. 880,157 of February 25, 1908, and 937,249, of October 19, 1909.

Referring to the drawings, Figure 1 is a side elevation of the full-stroke mechanism with the frame of the machine broken away to show the parts; Fig. 2 is a sectional front elevation taken on the line 22 of Fig. 1; Figs. 3 and 4 are front elevations with parts in section or broken away and Fig. 5 is an elevation of the hub of a detachable handle.

As seen in Figs. 1 and 2, 10 represents the frame of the machine. Loosely mounted in the frame is a rotatable sleeve 11 to a flange of which is fastened by means of rivets 13 the full-stroke sector 12. The sleeve 11 forms a bearing for the operating shaft 1 1, to which is attached by means of pins the Specification of Letters Patent.

member 15. The member 15 and the sleeve 11 are nested as shown at 16, but are inclependently movable. Mounted upon 15 is a segmental gear 17 which meshes wit-h a rec1procating rack 18, the latter being a means through which power may be applied to rock the member 15 and the shaft 14. This particular gearing forms no part of the present lnventlon. The member 15 carries the usual actuating lever 19 as shown in the Letters Patent cited above; and it also has a dependmg arcuate piece 20, and offset from the top of the segmental gear, a projecting lug 28.

As best shown in Fig. 3, the full-stroke sector has attached to it by means of bracket 24 and pin 22 an L-shaped lever 23 which is pivoted to the sector at 22. The lower arm of this lever is equipped with a double looking head adapted, as shown in Fig. 2, to enter a keeper 21 cut in the arcuate piece 20 of member 15, and also a keeper 26 cut in the side frame 10. The full-stroke sector is slotted as shown at 29 in Fig. 1 to permit free movement of the lever 23.

A collar 30 is rigidly mounted on sleeve 11 and is provided with a lug 32 in which is located a spring-pressed plunger 25 which bears against and normally forces the nose 34 of the lever 23 into the opening formed by the bore of the sleeve 11. On the flange of the sleeve a projection 27 is formed, as shown in Fig. 1, which is adapted to engage the lug 28 on member 15.

The handle shown in Fig. 5 is provided with a stub end 35 surrounded by a spaced sleeve 36 which telescopes the extremity of sleeve 11 when the handle is applied to the machine. The collar 30 is provided with the usual lug 31 and ratchet dog 33, by means of which the handle may be locked to the sleeve 11.

In operation, if the handle be applied to the machine, the stub end 35 after entering the sleeve 11 will force back the nose 34 of lever 23. This will move the locking head of the lower arm to the left as shown in Fig. at and cause it to enter the keeper 21, thereby locking together the sleeve 11 and member 15 including also the full-stroke sector. The power applied to the handle is transmitted through sleeve 11, projection 27 to the lug 28 on member 15, causing direct movement of the latter by means of the handle. Under these conditions the full-stroke mechanism is in an operative condition.

WVhen the machine is to. be driven by its power attachment and the handle is removed, the plunger 25 forces the nose of lever 23 upward thereby moving the locking head on lever 23 to the right as shown in Fig. 3. This movement disengages the full-stroke sector and sleeve 11 from the member 15 and at the same time locks them in a fixed position by means of the locking head engaging the keeper 26 in the side frame 10. The member 15, however, is free to be actuated by the rack 18, the lug 28-mcving downward away from projection 27 which is now locked to the frame through the means described above.

The arcuate piece 20 attached to member 15. forms a guard which prevents any engagement with lever 23 except at the point where the keeper 21 is located.
